hi,
         I have compiled the kernel 2.6.10 with KGDB
patches on FC3 .My KGDB connetion are made correct .
I have copied bzImage and System.map on test machine .
but when i press C for continuig no devlopment m/c
after  connection are made.It gives me kernel panic
error like this 

VFS: Cannot open root device "hda6" or
unknown-block(3,6)
Please append a correct "root=" boot option Kernel
panic - not syncing: VFS: Unable to mount root fs on
unknown-block(3,6)
 

my root partion  is on /dev/hda6.
My grub entry is like this.

         root (hd0,5)
         kernel /boot/vmlinuz-2.6.10 ro root=/dev/hda6

You might need initrd or make sure "ide" is configured
in your kernel.

Do you have /dev/console and /dev/null in /dev (not udev's files, but
spec files on /dev/hda6), this is known problem on fcs.
read http://www.fi.muni.cz/~xslaby/unpr/kernel.html, it's all in
czech, i haven't translate it yet, sorry, but find mkdir /tmp/dev

fedora core basically makes an initrd mandatory (udev and all); if you
had used "make istall" it'd have been set up for you fully automatic
including the bootloader
